|Table 2: Extraction yields and radical scavenging percentages of several extracts prepared by the extraction procedures E1–E6 from the olive wood sample A.|
|Extracts A1–A20 were prepared from the olive wood sample A, collected in April, 2003 (during the pruning period) at the village of Fuensanta, Jaén province, Spain.|
Procedures E1–E6 are detailed in Figures 1–6.
cYield is expressed as grams of extract per kilogram of olive wood sample.
dRadical scavenging percentage (RSP) is expressed as DPPH• scavenging (%). Values are means of three replicates ± SD (standard deviation).
dCommercially available rosemary extract was used as reference, at the same concentration (50 g mL−1).
